摘要

研究了热轧作为沉积后处理对以氮气为工艺气体制备的冷喷涂Al-6061镀层组织和力学性能的影响。采用不同程度的热轧,然后进行固溶时效热处理,以增强晶间结合,提高机械性能。该处理通过静态和动态再结晶使沉积层致密化,并引起晶粒结构的变化。显微硬度测量、静态拉伸测试、单轴疲劳测试、疲劳裂纹扩展速率测试和断裂韧性评估表明,材料强度、抗疲劳性和裂纹扩展行为都有显著改善。所提出的方法对于制造具有简单几何形状的大型部件是有效的。此外,它还可以作为一种手段,通过广泛的热机械加工,探索氮基冷喷涂镀层的显微组织和力学性能的上限。

Effect of thermo-mechanical treatment on the static and cyclic performance of cold sprayed 6061 aluminum alloy
This paper investigates the influence of hot-rolling as a post-deposition treatment on the microstructure and mechanical properties of cold sprayed Al-6061 deposits prepared using nitrogen as the process gas. Various degrees of hot-rolling, followed by solution-aging heat treatment, were applied to enhance inter-particular bonding and improve mechanical performance. The treatment significantly densified the deposits and induced changes in the grain structure through static and dynamic recrystallization. Microhardness measurements, static tensile tests, uniaxial fatigue tests, fatigue crack growth rate tests, and fracture toughness assessments demonstrated notable improvements in the material strength, fatigue resistance, and crack growth behavior. The proposed approach will be effective for fabricating large-scale components with simple geometries. Additionally, it serves as a means to explore the upper bounds of microstructural and mechanical performance achievable in nitrogen-based cold sprayed deposits through extensive thermo-mechanical processing.

期刊介绍: Typical subjects discussed in International Journal of Fatigue address: Novel fatigue testing and characterization methods (new kinds of fatigue tests, critical evaluation of existing methods, in situ measurement of fatigue degradation, non-contact field measurements) Multiaxial fatigue and complex loading effects of materials and structures, exploring state-of-the-art concepts in degradation under cyclic loading Fatigue in the very high cycle regime, including failure mode transitions from surface to subsurface, effects of surface treatment, processing, and loading conditions Modeling (including degradation processes and related driving forces, multiscale/multi-resolution methods, computational hierarchical and concurrent methods for coupled component and material responses, novel methods for notch root analysis, fracture mechanics, damage mechanics, crack growth kinetics, life prediction and durability, and prediction of stochastic fatigue behavior reflecting microstructure and service conditions) Models for early stages of fatigue crack formation and growth that explicitly consider microstructure and relevant materials science aspects Understanding the influence or manufacturing and processing route on fatigue degradation, and embedding this understanding in more predictive schemes for mitigation and design against fatigue Prognosis and damage state awareness (including sensors, monitoring, methodology, interactive control, accelerated methods, data interpretation) Applications of technologies associated with fatigue and their implications for structural integrity and reliability. This includes issues related to design, operation and maintenance, i.e., life cycle engineering Smart materials and structures that can sense and mitigate fatigue degradation Fatigue of devices and structures at small scales, including effects of process route and surfaces/interfaces.
